Ah so you're using worthless anecdotal evidence.
If my experiences to you are worthless, than so be it, that's your opinion. I would encourage you to go out and talk to people because I'd like to know what people are feeling and thinking about the Democratic candidates who have announced so far.
Among people who aren't Californians and aren't yet paying attention to an election that's 642 days away, how many people have heard of or know literally anything about Kamala Harris? 5%? 10%? Your sample is likely far, far too small to be indicative of how the Democratic primary voters will actually end up voting, never mind the fact that the very first primary is ~375 days away.
